An epidemiological model simulating the growth of a single grapevine stock coupled to the dispersal and disease dynamics
of the airborne conidia of the powdery mildew pathogen
Erysiphe necator
was developed. The model input variables
were either climatic (temperature, wind speed and direction) or related to the pathogen (location and onset of primary
infection). The environmental input variables dictated plant growth and pathogen spread (latent period, infection, lesion
growth, conidial spore production and release).
